The RT550 is a high quality machine suitable for both precision work and series construction.

Robust and efficient, it finds in the functionality of its command and movement organs the prerequisite for the development of more complex automatic work cycles suited to individual needs.

It is equipped with automatic work shifts with electro-hydraulic control and automatic descent of the wheel with pulses synchronized with transversal reversals.

The two spindle rotation speeds allow full use of the wheel.

The transverse and hydrostatically supported carriage and the controls are strictly centralized.

Linear diamond miller applied to the grinding wheel head to revive the grinding wheel.

Mechanical purifier for filtering fabric complete with motor, pump and 50L tank.
